My bag was delayed in London, so I didn’t have my belongings for 24 hrs after I returned home. They did find it and delivered it to my house, which was appreciated. The flight itself was great, and the staff was fantastic.

My bag was delayed in London, so I didn’t have my belongings for 24 hrs after I returned home. They did find it and delivered it to my house, which was appreciated. The flight itself was great, and the staff was fantastic.

The food was delicious. There has been a major improvement here in the last few years. Excellent, friendly service. An enjoyable experience.

The seats are very uncomfortable. They never have tomato juice. Usually late

Comfort. Not good very little space after the person in front of you lay back.

Crew very lovely. Arrived an hour late due to bad weather. We were given new tickets to an other flight but it could have been organised better, so we did not have to run through the whole airport to.

Food was very ordinary for premium economy, very small portions.

Our connecting flight was cancelled and it took us 15 hours to reach our destination.

The flight was surprisingly good, especially given initial experience. BA app is horrible as is their customer service. Online check in was a horrendous experience and when I phoned their customer service number, the live agent with whom I spoke was rude and dismissive. She did helpfully inform me that their IT people were working on a known problem related to online checkin. However, once she delivered that information, she curtly ended the call before I could suggest that since BA was aware of this, it should be posted on the app and online. I grudgingly flew BA this time - have avoided them for years because of past similar serial bad experiences. While this flight was fine, I’ll return to avoiding them in the future given the hassle experienced and rude personnel.

The entertainment offerings were not as good as I would have expected, but the service was very good, the crew helpful, and the flight on time! A very pleasant experience overall.

Sanitizing wipes would have been great while onboarding the flight.
